Web based bookmarks

I think it is great to have alternative ways to bookmark websites. However I prefer having them bookmarked through firefox for the convenience of having them on the page I'm looking at. I don't like the idea of having to open a new site to get to my links. I understand that computers crash, but that is why I keep a copy of all of my bookmarks in my Google documents! Online bookmarks are just not for me! But I encourage people to look into other alternatives since everyone has different things that work for them. You need to find what works for you and is comfortable!
